J Programming Language

Today beats yesterday as my fastest solve! Fairly short too, so I'll include my one-line solutions in-line. q[9] contains the input. Here is my updated visual of the Basilisk, which combines all my one-line solutions into a single, disgusting line of code!

Here's today's one-liners! Part 1 on line 40 and Part 2 on line 66.

Day 7 Parts 1 & 2 in a single line of Python (one-liners on lines 60 and 105; multi-line solutions above them).

This visualization shows the number of characters in my one-line solutions for each part of each day. I actually wrote up a small script to automatically count the characters, calculate their percent of the whole, pick a proportional colour on a rainbow gradient, and save the rainbow line in an SVG file so I can easily use that as the snake's fill colour. This way, I can update the visualization each day as soon as I finish coding the solution. (Don't worry, I won't spam the subreddit with them — it's just for my own antics!) The automation script is here, if anyone is interested.

Here's my one-line solution for Day 6, both parts in one, with q[6] as the input file:

A day late to post, but here is my one-line Python solution for both parts of Day 5! q[5] has the input file contents.

I know that title is scary. But just like last year, I'm trying to solve as many days of Advent of Code in a single line of Python as I can. Because of this restriction, I'm using __import__('re') so I can use RegEx in my solutions rather than using the import statement (since that would add an additional line). But this means I have multiple instances that look like __import__('re').findall(r'\d', l) within a single line (as seen here). My question is: what is the impact of this? Is it importing the module every time it is called, or is it considered fully imported after the first call and just referenced in future calls? Is there any other/better way of doing this?
